  • Arrangement for adjusting a powder flow in relation to the central longitudinal
    Patent number: 11890675
    Abstract: An arrangement for adjusting a powder flow in relation to the central longitudinal axis of an energy beam for a working head which is formed for powder application welding. There is a device for the two-dimensional or three-dimensional alignment of the powder supply in relation to the central longitudinal axis of the energy beam in a plane oriented at right angles to the central longitudinal axis of the energy beam. From one side, a linear beam is directed to the region in which the particles of the powdery material meet one another. At right angles thereto, there is arranged an optical detector array for locally resolved detection of intensities connected to an electronic evaluation unit designed to determine the shape, size and/or length of an irradiated region in which locally resolved intensities which exceed a predefinable threshold have been detected with the optical detector array.
